Deep below our feet, liquid iron swirls and roars, building the magnetic shield that steers compass needles and deflects cosmic radiation. Every so often – on timescales that laugh at human calendars – ...
We’re living through one of the most fascinating mysteries in Earth science right now. Scientists suggest that another reversal may be underway, potentially starting within 500 to 1,000 years, and the last reversal occurred 780,000 years ago. Meanwhile, our planet’s magnetic north pole is racing toward Siberia at unprecedented speeds, moving at speeds that ...
